Biological Activity

[Description]:

Quinethazone is an orally active diuretic agent and is also a weak inhibitor of carbonic anhydrase. Quinethazone can be used for hypertension research[1][2].

Signaling Pathways >> Metabolic Enzyme/Protease >> Carbonic Anhydrase

[In Vivo]

Quinethazone (50 mg/kg; p.o.; daily for 2 weeks) lowers blood pressure of renal hypertensive rats in association with a decrease in potassium but no change in water or sodium contents of aorta wall[1]. Animal Model: Five- to 6-week-old Long Evans male rats, hypertension model[1] Dosage: 50 mg/kg Administration: Oral, daily for 2 weeks Result: Had no significant effect on sodium or water distribution in arterial tissue of hypertensive rats, but decreased approximate 20% intra-cellular content of potassium
